Number 4-size Coffee Filter Cone, designed for manual pour-over coffee brewing, holds 8 to 12 cups. Brew single-cup coffee with each use—no more stale or burnt coffee made hours in advance. Make only what you need to reduce waste. Color: Black Size: 4 x 4 x 3.1 inches Material: Plastic This pour-over method, known as hand pour or hand drip, is a time-tested Japanese brewing technique developed to produce great-tasting coffee with full control over quality and flavor. Brewing is done by pouring a thin, slow, steady stream of water over ground coffee. To use, place the Coffee Filter Cone over a mug or carafe. Insert a paper or reusable filter and add medium-grind coffee (approximately 2 rounded tablespoons per 8 ounces of water, or to taste). Use just-boiled water to wet the grounds evenly, then let them bloom for 15 seconds. During blooming, the coffee expands and releases additional flavor. For optimal extraction, maintain a slow and precise water flow. Pour the remaining hot water slowly and evenly, starting from the center and moving outward in a circular motion. Allow the coffee to finish dripping—total brew time should be about 2 to 3 minutes. Remove the cone, discard the used grounds, and enjoy freshly brewed coffee immediately or chill for cold coffee drinks. This non-breakable, reusable coffee filter cone is a convenient portable option for coffee lovers on the go. It's easy to use, easy to clean, and dishwasher safe.
